'To NZZ lfm/1L may Concern.' A

Beitv known that 1` lliunrx WQSuAAn, a subject of theSu'ltan ot Turkey, residing ut Monroe. in the eountiof Snohoinieh und State of Washington, have invented new und useful Improvements in PnLunuatic-Tire Iieliners, ,of Whieh the following is a specification.

Thiginvention relates` to iinlnforemente in reliners for pneumatic; tires` und the object of thie improvement is to provide a leliner that is built up of a plui'nliliY of metallic sections whereby it will he absolulelil |iunetui-1` proof and will have gm-:d uwnrinf! qualities.

OLher znlruntaglx, eiific forma4 of construction rrihed and claimed.

rlhe invention consists in the novel con struction and combination of metallic und fabric parte to forni a re-liuer that is fienible, puncture proof and poseesses great wearing qualities.

In the accompanying drawings Figure l is view vin sectional perspective of a tirc that i5 fitted with this re-hner; Fig. 2 is a fragmentary view in longitudinal niidsee` tion of the re-liner; Fig. 3 is a View in eide elevation of one vof the metallic eectionfsl used on the inner surface of this` reliner; Fig. 4 is a )lan View of the device shown in Vig, 3; Flg. 5 is a fragmentary Sectional View illustrating the manner ot securing the me tallic section shown in Fig;A 3 to he bod)` oi' the re-liner; Fig. 6 is e fraginentar Y View in side elevation of one of the meta Sections that is adapted to be applied to the outside of the reeliner, and Fig. '7 is a fragnrntary sectional View of a detail of the invention.

Referring to the accompanying darwin s throughout which like reference numera s indicate like parts, the numeral 10 indicates etire casing of the usual form and 11 is en inner tire tube that may be placed within the casing in a Well known manner, the reliner that comprises this invention being '1nserted within the cesin between the inner wall of the casing and t e tube 11.

The re-liner consists of a body member 13 fabric, or au157 durable material that is sha ed to lit Within a pneumatic tire casing o the usuel form and has a plurali-ty of metallic sections 14 of reletively narrow Width Securedion its inside 'rwhlo in ilu nuwune hereinnfler flh- 56 surface at spaced inter-"als and extending around the inside of the tread portion thereof, and n plurality of similar metallic sections lliis'crurcd on ils outer u1-lace in offert poefitliiris with respect to said sectione on said inner surface ne more clearly illustrated in Fig. the edges of the sections l-l and 15 overlappingenthat a lack or sharp inei'rinnent Cnn not 'penetrate the re-liner at any point on the tread without encountering the metallic sevtionsand being prevented thereby from puncliiiing the inner tube,

The inner Seelioufi ll are preleralily bev vlc-d oilv on the cm'nei'sy n. indicated at 16. und nre ouch provillwl on wnh end ith on( nulli' diverted iii-onge l? ihm' uw adapted lo he clenched info llnrf' limi' bolli,I lln u# more clearly 'Almen in hir. ik ara-ure the lnllnllir :sertioinl lo the hod, nl' the ip liner The enter Section5; l5 have their rorners: beveled oil and are. provided nilh inuardl),Y directed prongs 18 that are "dapted to be clenched into the body ineinlier 13 ot the rc-liner in the Seine manner as the prongs 17.

20 is a piece of fabric or rubber composition that is adapted to be placed on the outside of the outer metallic sections 15 end sewed or vulcanized to the body ineniber 13 to protect the inner Walls of the tire casing from contact with the metallic members 15. and 2l 's a ainiilar piece of material that is served or rulrnnizcd to the inner welle of the re-liner to prevent the inner tube from coming in Contact with and wearing on the inner metallic nier-nimm lj,

22 is a Hap of thin inaterzall that le seu-'ed to one edge of the re-linei member 13 to overlap the space where the two edges ot the tirecasing unie together on the rim of the Wheel,

The metallic sectionslfl and 15 are prefer ably stam ed outof galvanized sheet metal that is rellittirely thin but is strong; enough to turn or bend the point of n tack or neil that may find its Way through the tire casing.

A l're-liner constructed as hereinbefore de scribed is fiexiblepso that it does not detract from the resiliency of the tire, is not expensire 0r difficult toconstruct, has reat Wearing qualities and will prevent oth punctures and blow-outs.

The tread portion of the reliner tively heavy Vand metal sections so that it will hold and protect the inner tube under the pressure of inflation even though the outer tire casn is almost worn out. The reliner thus eneles is rclais reinforced with the` the user to get more Wear out of his outer tire casings than could otherwise be done'.

Fig. 7 illustrates the structure of the protective coverings 20 and 21, such strueture serving to compensate for the unevenness of the metallic sections' of the reliner.

What I claim and desire to protect by Letters Patent is: l

A re-liner for pneumatic tires comprising an intermediate body ortion of strong iiexible material, a plura ity of narrow 111etallic stri s of arcuate shape extending transverse y around the interior of said body portion, sald strips being spaced a art and iaving outwardly directed integra prongs formed on the ends thereof "clenched into said body portion to secure said metallic strips against the inner face thereof, a plurality of narrow metallic strips of `arcuate shape extending in a' transverse dlrcction mosaici around the exterior of said bod rtioh in a position to brid the la); l getpseen said interior-1y' dis e meta ic'stri s, each of said exterior y disposed atrips lavin wadly directed prongs on the ends thereof clenched into said body portion to secure said last-named metallic strips against the strips. said coverings being transversely ao H AMDAN vW.
